Hi, There are loads of audio speed changer software on the web. These software seems to be able to change audio speed without changing the pitch of human voice...
I remember I came across this problem at Grade 7. That is exactly how we taught to solve the problem. Find the solution very intuitive. :)
Windowing, to my best understanding, is In Signal processing: 1.to trancate signals which are of your interest2.to reduce memory requirement and accelerate computation...
Hi,Sharan123,I think FFT(fast fourier transform) is an algorithm for implementing DFT(Discrete Fourier Transform). And IDFT - x(k)=1/N*summation (X(i）*exp(j*w0*i*K)...
Thank you for your time. But how can the second not efficient relative to single rate filter? Could you shed some lights on this?Chuan
Dr. mike, Do you agree with me on this? I think the upper bond is fs/2F0 for M. Here are my reasons. Here fs stands for sampling rate, F0 is the cutoff frequency...
